Acinetobacter corruptisaponis sp. nov., Isolated from a Spoiled Bath Lotion

Area of Science:

• Microbiology
• Bacteriology
• Genomics

Background:

• The genus Acinetobacter comprises opportunistic pathogens and environmental bacteria.
• Identification of novel species is crucial for understanding microbial diversity and potential risks.

Purpose of the Study:

• To characterize and name a novel Acinetobacter species isolated from spoiled bath lotion.
• To perform comprehensive phylogenetic, phenotypic, and genomic analyses.

Main Methods:

• 16S rRNA gene sequencing for phylogenetic analysis.
• Phenotypic characterization including Gram staining, motility, and growth conditions.
• Whole-genome sequencing and comparative genomic analyses (ANI, dDDH).
• AntiSMASH analysis for biosynthetic gene clusters.

Main Results:

• Strain DM2021935T, isolated from spoiled bath lotion, showed distinct phylogenetic placement.
• Phenotypic tests revealed Gram-negative, aerobic, non-motile characteristics.
• Genomic data (4.15 Mb genome, 41.8% G+C content) and low ANI/dDDH values confirmed novelty.
• Four biosynthetic gene clusters were identified, including non-ribosomal peptide synthetase.

Conclusions:

• Strain DM2021935T represents a novel species, Acinetobacter corruptisaponis sp. nov.
• This finding contributes to the taxonomic understanding of the Acinetobacter genus.
• The presence of biosynthetic gene clusters suggests potential secondary metabolite production.
